Question

Start with the Gizmo and select the "Color" Tab.
The fourth, and final, variable we are testing is the Temperature.
Move the light intensity to 100%
Move the CO2 level to 1000 ppm
Move the light wavelength to 400 nm
Start testing the the temperature my moving the bar all the way to the bottom, and start moving the bar up 5 degrees at a time.
Start at 0 degrees.

Your starting point should look like this image below:


Moving the Temperature 5c at a time, which Temperature produced the most Oxygen (O2)? Choose the best option
5 c
25 c
40 c
50 c

Answer 1

25°C.

Reason: O2 production rose as temperature increased from 0°C up to about 25°C (enzymes and reaction rates increasing), then fell at higher temperatures (enzyme activity drops/denaturation and other limiting effects), so the peak O2 output was at ~25°C.
